An explosion Monday damaged a public restroom at a controversial shrine in Tokyo that honors Japanese war dead, with police suspecting foul play. No one was injured.
The Yasukuni shrine, which honors 2.5 million Japanese war dead, including executed war criminals, has been the target of criticism from China and South Korea, which suffered from Japan's World War II atrocities and aggression.
Tokyo police said in a statement that they received a call about an explosion and smoke at Yasukuni. They said they suspected a "guerrilla" attack, implying some kind of subversive activity, but declined to elaborate.
Firefighters were also called to the scene and found the ceiling and walls of the restroom had been damaged.
